combustion pillard LeangasFlam-FIVES

Pillard LEANGASFLAM™ is an alternative fuel burner for blast furnace, coke oven gas and other types of low LHV (Low Heating Value) gas. It has been recognized as a proven technology for this application.

Firing without rich fuel support

Thanks to the ultimate design of the Pillard LEANGASFLAM™, most of the time, process gas can be fired without needing a rich fuel support such as natural gas, thus allowing customers to optimize operating costs.
